17-tone equal tuning has fifths very close to just-intonation (and 12-equal) fifths. Consequently we use the usual circle-of-fifths on a five-line-staff notation, with a twist of new enharmonics, caused by the accumulation of the difference in the size of the fifth. To figure out the enharmonic names of any closed circle of fifths, write out a portion of it, like: | |||
circle-of-fifths | |||
Cb Gb Db Ab Eb Bb F C G D A E B F# C# G# D# A# E# | |||
and then wrap it into a circle of the desired size (image forthcoming!). If you do this with 17, you will notice that Cb = A#...that's how big the value of "flat/sharp" is in 17. The closer two notes are in the circle, the more familiar to us their harmonic function. | |||
(need an image with the cents values, pitch classes, and ascending notation here). | |||
Note that C# is HIGHER than Db; the "half step"/"minor second" in 17 is twice as small as the "augmented unison"/"sharp"/"flat." Two sharp/flats add up to a minor third. Two "neutral thirds" add up to a "perfect fifth." These last two properties are shared by 17 and 24 (quartertones). | |||

Following the circle-of-fifths naming system for 17, the white keys of both pianos are tuned identically, to the (notated) C major scale. The pian called "flat" has black keys tuned to Db Eb Gb Ab Bb; the one called "sharp" has C# D# F# G# A#. IThis way we get 7+5+5 = 17 notes. | |||
In scores with separate staves for each piano, it is not necessary to spell chords with these distinctions; notating intervals in their most common appearance is recommended, e.g. "Eb to C on the sharp piano" rather than "D# to C." | |||
The pianos (baby grands, did I mention playing inside the piano is OK?) will be set up at a right angle, with flats on the left, sharps on the right, close enough that one person could play on both keyboards. | |||
DISCLAIMER: the 17-tone piano project is in no way affiliated with Rice University. it is not even an official Shepherd School of Music event, not being a senior or junior or masters or doctoral or faculty-sponsored recital. heck, it could completely fall through. but don't let that stop you. | |||
